i have a p28. just chipped it like two days ago. i can't rev pass 4k and check engine light is on. have i royally screwed up? i just cut the j1 jumper hoping that it will now work right. also will a venom control module make the vtec act up? my car seems sluggish even with a custom 2 1/2 exhaust with 4-2-1 ceramic coated headers, a high flow cat, cold air intake, apc wires, and ngk vpower plugs. any info is greatly thanked.

 

The ECU is in limp mode because there is a problem with the chip or the soldering. Can you take a picture of both sides of the ECU and post it here? The 2 1/2 inch exhaust and the CAI will make a stock engine seem sluggish because you will lose low end torque. Check the resistance of the plug wires. Remember APC=Another Piece of Crap.

 

i would take the pics, but my digital camera is down. i think it was the soldering, but if i cut the j1 jumper will it go back to norm? i will just have to take it to someone who can solder a lot better than me. it may just need to have the solder gone back over it. and even though i lose the low end i really don't pick up much top end, not to mention i have been having prob with the plug and the 3rd cylinder. i have fouled it maybe 2 or 3 times and i have ran colder and hotter ngk plugs. so i think it may be a combination of the rotor button, dist cap, and the wires. thanks

 

If you cut J1, yes, should revert back to stock program.

 

thanks i just cut the wire that was in j1 hopefully i can test it out before i go to work tomorrow. next time i go to a pro to get it soldered and watch them.

 

you definitely need proper equipment in order to solder printed circuits.
